World War 1 Practice Test

U-boat is the term for German submarines in World War I. It comes from German Unterseeboot, meaning undersea boat, and became the iconic label for Germany’s submarine fleet as it aimed to cripple Allied shipping. While “submarine” is a general term for underwater vessels used by any country, U-boat specifies the German boats of that era. A destroyer is a fast surface warship used to protect ships and hunt submarines, not the submarines themselves. A raider refers to certain surface ships used to attack merchant vessels and isn’t the standard name for Germany’s submarines.
